Display Device Transmission Layer for Camera Light and Window Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in tightly supporting windows while maintaining the light transmission characteristics of cameras, which affects structural stability and image quality.
Innovation Solution
A display device design that includes a panel, a camera, a polarization layer, a transmission layer with high light transmittance (90% or more), and a coating layer with a larger area than the panel, where the transmission layer overlaps the camera and supports the coating layer for improved structural stability and light transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a layer capable of supporting the window is disposed to tightly support the window, then structural stability is improved, but light transmission characteristics of the camera deteriorate
Solution Approach 1:
The patent applies local quality by making different regions of the support layer have different optical properties. The first support layer (first region) has high light transmittance to maintain camera performance, while the second support layer (second region) has different properties for structural support. This spatial differentiation of material properties resolves the contradiction between structural stability and light transmission.
Solution Approach 2:
The patent uses composite materials by combining multiple support layers with different characteristics. The first support layer and second support layer are composed of different materials or have different structural properties, allowing the system to simultaneously achieve both structural stability and high light transmission in different regions where the camera is located.
2Reliability
If the window is tightly supported to improve structural stability, then reliability is improved, but manufacturing complexity increases
Solution Approach 1:
The support structure is segmented into multiple distinct layers: a first support layer and a second support layer. This segmentation allows each layer to be optimized for specific functions (light transmission vs. structural support) and simplifies the manufacturing process by enabling independent fabrication and assembly of each layer, rather than requiring a single complex support structure.
3Illumination intensity
If a transmission layer with high light transmittance is used to improve camera light transmission, then light transmission characteristics are improved, but structural support capability is reduced
Solution Approach 1:
The patent merges multiple support layers with different functions into a unified support structure. The first support layer provides high light transmittance for camera performance, while the second support layer provides additional structural support. Together, they form a composite support system that achieves both high light transmission and adequate structural strength, overcoming the limitation of using a single layer.
